The invention embodies a cup-shaped disc having the base 12 and the sidewall 13, this side wall 13 being cut away throughout a portion of itslength as at le. Rotatably mounted in the 65 disc so as to rest upon thebase l2 is a cup-shaped disc having the base 15 and the side wall 16. Astud 17 is secured to and projects outwardly from the side wall le so asto ride in the cut away portion or slot 14. A nut 18 is threaded on thestud 70 17 and when threaded against the wall 13 will serve to lockthese discs in fixed relation to each other.

A rod 19 projects through the base 15 of the inner disc and is xedlyattached to the base 12 75 oi the outer disc. Fixedly mounted on the rod19 so as to engage the upper face of the base 15 is a head 20 so thatthe discs will be prevented from moving axially of each other.

Extending upwardly from the head 20 and S0 embracing the rod 19 is atapered sleeve 2l about which the wisp of hair to be curled is Wound.This sleeve 2l is knurled on its periphery adjacent its upper end as at22 and at its upper end this sleeve is hollowed out to provide a socket23.

A sleeve 25 is adapted for iitting loosely in the socket 23. Theopposite ends of this sleeve 25 are slotted as at 26 and 27 so as tostraddle the pin 24 which projects outwardly from the periphery of therod 19. A curved spring 28 is se- 90 cured at its end 29 to the sleeve25 and coiled partially around this sleeve with the free end 30 normallyin engagement with the inner surface of the socket 23. A cap or spacedsleeve 3l is held in position over the upper end of the sleeve 25 by 95means of the nut 32 which is threaded on the upper end of the rod 19.Since the slotted ends or" the sleeve 25 straddle the pin 24 it isobvious that the sleeve 25 cannot rotate about the rod 19 which projectstherethrough. On account of 100 the engagement of the free end 30 of thespring 28 with the inner surface of the socket 23 the sleeve 21 will berotated only in one direction around the rod 19.

In the form shown in Fig. 5 it is possible to ro- 105 tate the sleeve 2laround the rod 19 in a clockwise direction. An attempted reverserotation would cause the end 30 of the spring to snag against the innersurface of the socket 23 and bind so as to prevent the reverse rotation.When free end of the spring 28.

it is desired to have the sleeve 2l rotated in a reverse direction aboutthe rod 19 the sleeve may e removed and placed in 'the socket 23reversed end for end so that the spring 28 would extend in the directionshown in Fig. In such a form the sleeve 2l may be rotated in a counterclockwise movement around the rod 19 but not in a clockwise direction.The removal replacement of the sleeve is a simple operation as it is butnecessary to remove the nut 32 and the cap 31 in order to obtain accessto the sleeve 25.

As shown in Fig. 2 the bottom 15 oi the inner disc is provided with aninwardly projecting slot 33 and the bottom l2 oi the outer disc isprovided with a similar slot 3e. When these discs are moved to positionso that these slots are in alignment the wisp 35 of hair which is to becurled may be engaged and securely locked in position so that the discbottom l2 is held in closed engagement with the scalp by moving thediscs relatively to each other until the wisp of hair is securelyclamped in position. These discs may then be locked in this clampingposition by tightening the nut i3 on the stud i7.

To wind the wisp oi hair about curling prong or sleeve 2l we provide acurler embodying the hook 36 formed from wire which is carried by theresilient metallic sleeve 37 formed doubling the piece of resilientmaterial upon itself. A screw 38 is provided and is projected throughthe doubled over end ci the cari r 37 and provided with a nut 39 so thatits irictional engagement of the sleeve 2l may be regulated. rhe ireeends of this doubled over carrier are curled at 40 to provide enclosuresfor the reception oi the wire ends which are curled to form the windinghook 3G. Tongues 4l and 42 are formed on the upper end of this carrierand bent around the sleeve Z1 so as to resist a tilting strain which maybe transmitted to the carrier 37 the hair is being wound. When thestrand oi hair has been ilrmly wound about the rod or sleeve 3i it maybe moistened with a suitable inoistening lotion and thereupon a Jfeltwasher 43 is pressed downwardly so as to rest on the upper surface oithe bottom i3 of the inner A wrapping cloth or ribbon which haspreviously been urated with a suitable lotion is then wound around thehair so as to entirely enclose the same. In order to facilitate theenclosing of the wound strand or wisp of hair we have found it desirableto form the winding cloth or ribbon from a body 44 having its ends 45and 4G out diagonally so that in winding the diagonal cutis placedparallel with the plane of the disc l5 and the winding proceeded with.When the winding is complete the ribbon will terminate with its otherdiagonal end lying in a plane parallel to the plane of the 13 and thediagonally out ends forni narrow strips which permit of an easy windingand secure binding. When this been done we provide an enclosing tube 47.The hair is then wound tightly about the sleeve or rod 2l by grippingthe knurled portion 22 of the sleeve 2l and rotating it about the rod1S. lts direction ,o rotation will, of course, have to be in the samedirection as the winding of the wisp o hair or strand of hair 35 so asto tighten this strand. lts direction of rotation can be only in thisdirection it the operator has wound the hair in the right directiondependent upon which end of the sleeve 25 has been placed downwardly.Considerable strain and tension will thus be placed upon the curl and areverse rotation of the sleeve 2l will be prevented by the The enclosingtube 47 is slipped over the curled and wrapped hair as shown in Fig. l.This enclosing tube 47 is provided with a flange 48 projecting outwardlyfrom which is a locking tongue 49 which engages the wall 16 of the innerdisc when rotated relatively thereto so as to iirmly bind the tube 47 inengagement with the gasket or washer 43 and form a steam tight andliquid tight connection so that it is impossible to burn the scalpthrough the escape of liquid or steam. This enclosing tube 47 isprovided with a spring 50 which is attached thereto at one end and freeat the other. This spring is bow-shaped intermediate its ends so thatwhen the tube 47 is inserted into the bore 5l of the heating element 52the spring 50 will serve to prevent its undue removal therefrom.

ln carrying on a curling operation it is quite important that the curlbe heated to a predetermined temperature. If this temperature isexceeded to any extent a burning of the hair may result and ii thetemperature is not reached a proper curling of the hair cannot beeffected. In a curling machine a number of heating elements are providedand seldom, if ever, are all of these heating elements in use in asingle heating operation, but they are all connected to the same sourceof heat so that the temperature of each is the same. We have provided aheat indicator which may be inserted in one of the idle heat units sothat when the proper temperature has been reached this indicator willindicate the same and the operator may then know ing operation iscompleted. This heat ci comprises a tube 53 preferably iilled with apowdered graphite 53. and in which is inserted the lower end of themercury tube 55 which is supported by the extension 56 of the tube shell53. The mercury tube 55 will be suitably graduated to indicatetemperature conditions. A spring 54 connected at one end to the tube 53is iree at its opposite end and bow-shaped intermediate its ends so asto engage the inner surface of the bore 5i of the heating element 52 andretain the heat indicator in position therein. The upper end 57 of thisspring 54 is angularly turned. to form an abutment so that a slippingdownwardly of the tube 53 for any reason may be prevented. With acurling device of this class a. smpie and easily operated mechanism isprovided and one in which a very desirable type ot curl may beaccomplished. Safety is also allorded in that a leal; of liquid or steamagainst the/scalp is avoided and due to the use of theheat indicatordescribed the proper temperature will'. always be arrived at.
